Some additional detail to what Dennie is saying: There are gradable adjectives (which can be modified to express their intensity) I am tired, I am very tired, I am extremely tired There are non gradable adjectives (which cannot be modified since they're already extreme) This is amazing, This is terrific, This is fabulous, I'm exhausted Non gradable adjectives can be: classifying adjectives: married, wooden pregnant extreme adjectives: brilliant, excellent, disgusting absolute adjectives: dead, supreme, final And finally there are gradable/non gradable adjectives, that is, adjectives that sometimes behave as graded and sometimes as non graded: She sounded slightly foreign to me (it's graded here by "slightly") He is working on foreign policy (cannot be graded) Note that many non gradable adjectives can nevertheless by the adverb "really" - I would say just the "extreme" ones not the other two. I hope this helps.

In practice I'm not sure how useful it is to make such a distinction. Even if "very" sounds strange there are other words that are often used instead. "Truly, truly, truly outrageous!" -Jem "And she's not only merely dead, she's really most sincerely dead." - Munchkin Coroner

Hi Lolita. Gradable adjectives like: big, good, happy...are adjectives where you can add the words quite, very or really to show how big, good or happy they are. Ungradable adjectives don't normally have quite, very or really before them because they are already extreme: enormous, delighted, fantastic, etc.

gradable adjectives are adjectives that you can add "very" to; for instance: very cold, very hot, very lonely...These adjectives have intensity or can show different degrees of being "fill out any adjective here", e.g. cold. non-gradable adjectives are adjectives like: married, dead... You can't be very married or very dead. There are no different degrees of being married or dead. Hope this helped.

I do not know what either of these are and I speak English, so maybe it is not important, sorry!
